Water quality is fundamental to our regional agricultural and food production industries, is of significant concern for Midwestern and Gulf environmental health, and is essential for other regional economic interests that include recreation. The data revolution presents a new and exciting opportunity to address water-quality challenges. Various efforts are underway to store and standardize the large volumes of public water-quality data collected through existing federal, state, and local programs. However, new forms of water data from on-site instruments, satellites, and citizen-science programs are rapidly increasing, and many of these data streams originate in the nonprofit, academic, and private sectors with disparate data standards.
